Add .gitattributes file to compensate for .editorconfig end_of_line on Windows

[segevfiner]

Please describe

By setting end_of_line = lf in .editorconfig, the editor and prettier will write lf line endings, but Git on Windows is often configured with core.autccrlf=true which will check out the files with crlf line endings. To compensate for that, the repository needs to include a .gitattributes with *.{js,jsx,mjs,cjs,ts,tsx,mts,cts,vue} text eol=lf (Or otherwise if that glob syntax is not supported in gitattributes) or maybe just * text=auto eol=lf as recommended by prettier? .
